Videos in the public domain are no longer subject to copyright laws, and you may use them freely without permission and without fear of legal repercussions. You may remix public domain videos into new works. When a video creatorâs copyright expires, that video automatically becomes part of the public domain. Also, anything produced by the U.S. government is automatically in the public domain. Sometimes videos become public when the original copyright holder fails to complete the necessary paperwork to renew the copyright.
